How long does a Calgary roof replacement take?

Most single-family Calgary homes are done in 1–2 days. Multi-tier or cedar shake homes take 3–6 days. We never leave a roof open overnight.

What's the best shingle for Calgary's hail?

Class 4 impact-rated shingles. IKO Nordic, Malarkey Vista AR, Owens Corning Duration Storm and BP Mystique are the four we install most. They pass UL 2218 50mm hail testing and often qualify for an insurance discount.

Do you remove the old shingles or roof over them?

Full tear-off, every time. Roofing over is allowed by Calgary bylaw but voids most shingle warranties, doubles the load on your trusses, and traps moisture in the deck. We won't do it.

Will my home insurance cover a hail-damaged roof replacement?

In almost every case, yes — hail damage is covered by virtually all Alberta home policies. You typically pay only your deductible. We meet your adjuster, document the damage, and supplement the claim. Read our insurance claim guide .

What kind of warranty do I get on a Calgary roof replacement?

10-year workmanship warranty from Good Roofing in writing, plus the manufacturer's material warranty — typically 30 years on standard architectural, up to 50 years on premium Class 4 shingles.

Do I need permits for a roof replacement in Calgary?

Yes — the City of Calgary requires a roofing permit. We pull it for you and include the cost in our quote.

Why Calgary roofs need Class 4 impact-rated shingles

Calgary has the highest hail-claim frequency of any major city in Canada. A standard 3-tab or Class 1 architectural shingle is rated for ~25–30 mm hail — exactly what we see every June and August. Class 4 shingles like IKO Nordic and Malarkey Vista AR pass UL 2218 testing for 50 mm hail and use a polymer-modified asphalt that resists granule loss. Most Calgary insurers (TD, Aviva, Intact, Co-operators) give a 5–25% discount on your home premium for Class 4 — meaning the upgrade often pays for itself over the life of the roof.

Insurance hail-claim roof replacements in Calgary

If your roof was damaged in a Calgary hailstorm, in most cases insurance pays for the full replacement minus your deductible. We meet your adjuster on the roof, document every hail strike, advocate for the proper scope, and supplement the claim if the adjuster misses items (a routine occurrence). Most clients end up paying only their deductible. See our insurance claim help page.

“Got three quotes. Good Roofing wasn’t the cheapest but they were the only ones who actually went on the roof and put a fixed price in writing. No surprises.”

Dave K. · Tuscany

“Emergency leak the night of a Chinook windstorm. They had a tarp on the roof by 11pm. Did the permanent repair two days later for exactly the quoted price.”

Priya R. · Bridgeland

“I’m a 71-year-old widow and was terrified of being upsold. The project lead walked me through every line item and even fixed two soffit screws for free.”
